In New Vegas, for example, having to go all the way around an unclimbable mountain was always irritating for me. Especially when my goal was just on the other side. Seeing as Skyrim is mostly mountains, I really hope it doesn't make travel more difficult. It would also bother me when I fell down a mountain or cliff, then had to spend hours (exaggerated) to find my way back to the top or around to a familiar location.
Whoever said 'nothing's impossible' never tried nailing Jell-O to a tree.
Please dont....When ever I think of the invisible wall around Quarry Junction i am filled with such rage I want to punch things....People, children, babies, old people....ANYTHING! Apart from animals...thats where I draw the line.
HOLY ****! What is this? Forged in Gods very flames! Do mine eyes tell me lies? A new Elder Scrolls game? Time is nigh, I must fly, Venture forth on my quest!
